hello everyone, i read and see many threads about unlocking the gtx465 to gtx470 but in same time i read not all GF100 GTX465 can be unlocked to GTX470, so guys i need your help here cuz im think about getting two GTX465 on SLI and unlock them to GTX470 in SLI and i want to overclock them , is that can be happen and which brand i should get

The only one that seems to be for sure is the MSI Twin Frozr all copper version. Looking at the Zotac picture, it looks like that one (that they took the picture of) can unlock due to it having all of the capacitors on the backside of the memory chips.

Even for the Twin Frozr Copper cards, there seem to be a handful out of the 2500 that could not be unlocked, so it's not a 100% sure thing, but you will have a very high chance of doing so. They are sold out at Newegg though, so you'll have to buy from somewhere else.

The other ones that have been unlocked are earlier batches of PNY and PoV 465s that have the black PCB (not blue), but those are more of a gamble since Newegg have been known to show a picture of the PNY card with a black PCB, but ship one out with a blue PCB.

In the end, it's a nice bonus if you get a 465 that can unlock, but if you did not want a 465 in the first place, I would not risk buying one with the hope of unlocking it into a 470. The risks are high and the cards that can be flashed are lower binned samples anyways that generally don't overclock as well as stock 470s. With all the deals on GTX 470s these days, I would just buy a legit 470 instead of hoping to unlock a 465.

The only exception to this may be the Twin Frozr 465 Golden Edition. It has an unusually high rate of unlock (I'm sure MSI intended it to be that way, just as AMD did with the X2 555) and an awesome cooler. So basically you're getting a limited edition Twin Frozr 470 for $100 less than retail.

I think you would be better with the two 460's as they scale beautifully (may get more overall performance out of a pair), use much less power, and should OC nicely. OCing a card is a sure thing, while unlocking a 465 is most likely not going to happen. As I understand, those GPU cores are mostly physically disabled which cannot be altered.

Scaling isn't the issue, 465s actually scale similarly as 460s in SLI. It's just that whether stock or OC'd, a 460 1gb will be just as fast as a 465 while using a lot less power and putting out a lot less heat and noise.

The only MSI one that can unlock is the copper twin frozr one. Not all 465s with black PCB can unlock, only the earlier batch PNY and PoV ones.

thanx bro, in fact i have now Zotac GTX480 AMP but i see i can't do SLI with same card in future using same mobo i have now cuz the the card take 3 slots, in same time i love do stuff and trays like this cuz it save more money to me, in my country i can't do easy shipping and if i ordered something from newegg using our clients it cost me same thing, gtx465 cost here 350$ ,gtx470=500$ , gtx480=700-800, so i can sell my card at 700$ and pickup two gtx465 and unlock them as 470 with saving 300$, but seems it isn't happen now

Its so darn easy to do it yourself with nvflash, but if you need the free games in the package its a good deal. He also claimed the MSI warranty would still be valid since NCIX did this as part of a retail sale.

Well, if you can still get a Twin Frozr GTX 465 GE that'd be your best bet I think. Newegg's out of stock now, but there are still some stores online that have them. Dunno how that shipping thing's gonna work out though

You have to have the 10 RAM chips before you can even attempt it. 90% of the newer 465s ship with 8 and there are pictures showing how to identify these cards without even taking the heatsink off. Basically the resistors arent there and so therefor the RAM chips arent there. Its pretty much a guaranteed that if you try to flash to a 470 with these cards they will be bricked and you better have a backup card to reflash.

Being an owner of an eVGA 465 i decided to look into it, as well as ask some eVGA guys personally while i was at Quakecon.

You cannot tell if the 9th and 10th RAM chips are there by looking at the "resistors" (actually they all are capacitors) on the backside behind the supposed chips. For example, see the board pics in TPU's review on 8-chipped Zotac 465. You'll see all the caps in place but no RAM chippery.
